Abstract: | This paper discusses exposure determination for digital cameras, beginning with a tutorial on exposure control and the factors
affecting the quality of still captures, especially exposure index. It presents a psychometric model for the overall quality
of digital camera images as a function of motion blur and exposure index. A motion-aware exposure control algorithm based
on that model is described for exclusively ambient illumination and then extended for combined flash and ambient illumination.
Results from a field test with a modified consumer camera quantify the effectiveness of the algorithm. |
